FIELD: construction.
SUBSTANCE: device to beat icicles from building roofs comprises a fuselage, a bearing screw with blades from polymer composite material, a four-blade X-shaped steering screw, a control system, a non-detachable fixed plant for an actuator. In the fuselage there is a receiver comprising an inlet hole connected to a source of compressed air, and three outlet holes. Two of them are connected by air ducts with adjustable nozzles placed in working cylinders of drive shafts of the bearing and tail screws. Turbine blades are rigidly fixed on surface of shafts. The third outlet hole is connected by an air duct with a pneumatic tool placed on the non-detachable movable plant. Adjustable nozzles of air ducts, screws, the movable site and the pneumatic tool are connected with a control panel. At both sides of the fuselage there are journals, where eyes are installed as movable and joined with a cargo hopper.
EFFECT: increased operational reliability of a roof.
